Faced & Unfaced Fiberglass Insulation

Faced MBI Fiberglass Insulation

Bay Insulation's faced MBI fiberglass is a resilient, flexible fiberglass blanket laminated to a high quality vapor retarder facing. It is the most common and cost effective solution used for insulating pre-engineered metal buildings.

Faced fiberglass can be installed as a single layer, or combined with unfaced MBI fiberglass and various support hardware to create a "High R-Value System".

Custom Lamination and Packaging

Every order is custom laminated to fit your building dimensions and criteria. Each roll is individually tagged to identify its intended location in the building roof, sidewalls and endwalls.

Single 6"
No-StapleTab
First roll of insulation is installed with 6" tab as leading edge. Next roll is nested over tab from first roll.
Single 6" "Reinforced"
No-Staple Tab
Mylar reinforcement is added at 6" tab to provide rigidity.
Single 6"
"Self-Adhering"
No-Staple Tab
And adhesive strip with removable backer is added at 6" tab for adhering tab to adjoining roll.
Double 12" or 15" Tabs For use with double fiberglass layer "High R-Value" systems. Tabs from adjoining purlin spaces are lapped together over purlin.
Tuck Tab For use in single layer application where a single 6" tab is folded under the facing of the adjacent roll.

Facings

Faced MBI fiberglass is available with a variety of facing finishes. Vapor retarder facings reduce the flow of interior moisture to the fiberglass and metal siding, protect the fiberglass, and provide an attractive interior finish for the building.

NAIMA

NAIMA 202-96® fiberglass metal building insulations are blanket insulations engineered specifically for metal building construction. These insulations are certified by the NAHB to meet the 202-96® standard for flexible fiberglass used in Metal Buildings and are engineered and produced to maintain their stated R-value after the rigors of facing lamination, shipping, storage, and handling that occurs during installation. Bay Insulation uses NAIMA 202-96® fiberglass when laminating R-10, R-11, R-13, R-16, R-25 and R-30.

NIA

The NIA standard provides a basis for quality control procedures of the lamination process and for certifying post-laminated R-Value. (National Insulation Association) Every Bay plant is compliant with the standard for "Certified Faced Insulation".
